Evaluation of inflammatory and hematological parameters in patients diagnosed with COVID-19.

INTRODUCTION: This study aims to research the effects of hematological and inflammatory parameters on the prognosis of COVID-19 disease and hospitalization duration. METHODOLOGY: One hundred and eighty-six patients with COVID-19 and a control group consisting of 187 healthy individuals were included in the study. Hematological variables and inflammatory parameters of the patients were recorded on the first and the fifth days of hospitalization. RESULTS: White blood cell count, lymphocyte count, and platelet count were statistically lower, and mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) levels were higher in the patient group compared to the control group. It was observed that the neutrophil count and MPV level were lower, and the platelet count and ferritin level were statistically higher on the fifth day of follow-up compared to the admission day. In contrast, there was a significantly positive correlation between the duration of hospitalization and the fifth day D-dimer (r = 0.546, p < 0.001) and ferritin (r = 0.568, p < 0.001); in addition, there was a negative correlation between the duration of hospitalization and admission day lymphocyte count and the fifth-day lymphocyte count. CONCLUSIONS: Increased levels of ferritin and D-dimer, and decreased count of lymphocytes are among the important factors affecting the duration of hospitalization for COVID-19 patients. Furthermore, we think that neutrophil count and MPV levels are low, and platelet count and ferritin levels are high during the disease. Therefore, these parameters can be used as prognostic indicators of the disease.

Risk factors associated with gallstone and biliary sludge formation during pregnancy.

AIM: To define the risk factors in gallstone and sludge formation, and to investigate the incidence of gallstone and biliary sludge formation during pregnancy in a group of healthy pregnant women. METHODS: Sixty-nine healthy pregnant women in early gestation and 28 nulliparous healthy controls were enrolled. Gallbladder volumes, gallbladder ejection fraction (GBEF), serum triglyceride and cholesterol levels were determined in both groups. In the pregnant group, repeated measurements were performed immediately after delivery and compared with initial levels. Risk factors, which are associated with gallstone and biliary sludge development during pregnancy, were determined by linear regression analysis. RESULTS: No statistically significant difference was observed in the assessed parameters of pregnant women in early gestation and controls (both P > 0.05). In the pregnant group, gallstone and biliary sludge development during pregnancy were detected in 6.3% and 10.9% of cases, respectively. The detected parameters were significantly higher early after delivery than in early gestation, while GBEF was lower (both P < 0.001). Lower GBEF was the most significant factor (P < 0.001) associated with gallstone and sludge formation during pregnancy, while multiple childbirths was the other (P = 0.04). CONCLUSION: Decrease in GBEF is the most significant risk factor for newly developed gallstone and sludge in pregnant women, while multiple childbirths is the other but less important risk factor.
